The points have not changed since G5, so that is not really a solution.
The only thing that has changed as far as I can tell is there is a wider range of opponents available. So you can squeeze available opponents into a tighter group, i.e. have a refresh all be within say 50 or 100 arena points as you. Or squeez them so that all opponents are within 10 areana points as you and it would always be +-10. That would be one option.
I can see how some players may prefer that. But i disagree it would be an 'objectively' better system. The way it is now I have opponents that I can score only 4 points on, and I'm more wary of them than I am off the opponents I can score 17 points on. I fight more opponents at the top end of the scale than the lower. Squeezing opponents areana point range back to earlier ranges would take away that adantage. Squeeing them to +-10 would be silly.
As far as getting the same points, let me try this imagery; Imagine we are walking up a set of stairs and we are on the same step. To proceed we must defeat an opponent. I defeat an opponent 10 steps above us, and you defeat an opponent 10 steps below us. Several people have stated it is unfair unless we both get to take the same number of steps up the stairs after our victories. I call BS on this. That would be unfair as could be.
As far as the actual rewards, medals and forge materials, it's the same reward regardless.
What are the alternatives? Player Power, Team Power, and Arena Points! Are there any other? I completely disagree that anyone should progress the same amount for defeating someone 10 steps below them as 10 steps above them.
